I will prevent to happen in all my SW releases (counter = 0 )
Yes, I meant a similar stuff to JiffyDOS with the parallel TCBM.
The 4.5 times speed increase compared to the damn slow 1541 IEC is not impressive at all TCBM has 8 bit data bandwidth, while the IEC uses only 1 bit for data. The protocol is just too complex. The design team had a chance to develop a blazing fast device could directly load data into the computer, as they had everything. 8 bit data bus, two handskahe bit, extra control board, simple communition channel (no daisy chain) This chance lost, despite using a big and arkward controller paddle.
The transfer speed is even slower than IEEE-488, was already a 10 year old protocol. Instead of using the existing IEEE-488 protocol, or creating a faster version, they created an even slower, new protocol, with full of unnecessary handshakes. I am not impressed.
